Claims. 1

The present invention relates to storm window constructions and more particularly to construction readily adjustable for fitting window frames of varying dimensions.

An object of the present invention is to provide a storm window which is of simple construction and that can be adjusted to window frames that are out of square or of varying dimensions and wherein the storm window can be sealingly engaged with the window frame.

A further object of the present invention is to provide a storm window in which a flexible transparent sheet is employed whereby the same can be clampingly received and held by the storm window frame elements providing blast protection.

Another object of the present invention is to provide a storm or blast window that is of adjustable form and adapted to be positioned in the frame of a window inwardly of the conventional windows mounted in the frame, enabling mounting of the storm windows in the frames from :the interior of a building without the use of special tools or special fittings.

A still further object of the present invention is to provide a storm window frame having slots formed therein, the slots of the frame end elements being in a plane displaced from the plane of the slots in the frame side elements and said elements having their ends formed with cooperable lap joints whereby when the frame elements and transparent sheet are assembled, limited distortion of the sheet is effected at the corners thereof, the sheet being securely held from movement relative to the frame elements.

The best form in which I have contemplated applying my invention is clearly illustrated in the accompanying drawing, wherein:

Figure 1 is a front elevational view of the invention;

Figure 2 is an enlarged detail of the corner construction of the storm window;

Figure 3 is a horizontal detail sectional view taken substantially along the plane of line 3-3 of Figure 2;

Figure 4 is a vertical detail sectional view taken substantially along the plane of line 4-4 of Figure 2; and

Figure 5 is a vertical detail sectional view taken substantially along the plane of line 5-5 of Figure 2.

Referring more particularly to the drawings wherein like numerals designate like parts throughout, the numeral l0 designates generally the storm window construction of the present invention.

' with horizontal and vertical slots 35 and 32, and

' faces 22.

33 and 31, respectively, in the recessed portions thereof for underlying the openings of the end elements. Bolts 34 and wing nuts 36, are employed for adjustably securing the frame elements in preselected relation to each other.

Secured to the outer edge surfaces of each of the frame elements are pieces of weather stripping 38, 40, 42 and 44, such as felt. The

overlapping portions 46, 48, 50 and 52 are trimmed 'off after adjustment of the frame elements.

Looking now at Figure 4, it will be seen that the side elements l6 and I8 are provided with slots 54 which are longitudinally extending and lie in planes displaced from the plane of the lap Similarly the end elements 12 and [4 have slots 56 formed therein which lie in planes displaced from the planes of the lap faces 20.

Wooden spacers 58 can be provided to fill in the spaces formed by the adjusted frame to give a smooth continuous surface for painting.

A transparent flexible sheet 60 is disposed with its edge. portions received in said slots 54 and 56 so that when the frame elements are clamped together, the sheet 60 will be deformed at the corner portions thereof by the lap faces as shown in Figures 3 and 4. Thus, the sheet will be effectively held from movement relative to the frame element.

Having described the invention, what is claimed as new is:

1. A storm window construction comprising end and side frame elements, means slidably, clampinglyand adjustably connecting the frame elements together to provide a frame whose shape may be varied, the ends of each of said end and side elements being recessed, the .ends of said side elements overlapping the ends of the end elements, said frame elements being slotted; a flexible transparent plate having its marginal edge received in the slots of said frame elements, and said transparent plate being clampingly held between the overlapping ends of the elements upon clamping of said frame elements together by said means.

2. A storm window construction comprising end and side frame elements, means slidably, clampingly and adjustably connecting said frame elements together to provide a frame, the ends of each of said end and side elements being recessed with the ends of said side elements overlapping the ends of said end elements, said frame elements being slotted, a flexible transparent plate haying .,its margina1 edges received: in the slots of said frame elements and itscor- 1(1 ners received between said overlapping ends, the slots in said end and side elements being formedin planes displaced from the planes .-of-the .recessed end portions whereby when said means is adjusted to clamp the overlapping. ends tQ,-..15 gether the slots of the end elements will lie in, a plane displaced from the plane of the slots in the side elements, thereby submitting the plate-to; a limited degree of distortion for securing the ma mm.
